1st option

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion , that is

ΔAXY is similar to ΔABC. triangles ABC and AXY, №18011278, 22.05.2022 20:31 = ΔAXY is similar to ΔABC. triangles ABC and AXY, №18011278, 22.05.2022 20:31 ( cross- multiply )

AB × AY = AX × AC ( divide both sides by AY )

AB = AX times AC over AY

To determine the length of segment BC, we can use the given information about the similarity of triangles ΔAXY and ΔABC.

Let's analyze the options one by one:

a. BC = AC

This option assumes that BC is equal to AC. However, since we know that ΔAXY is similar to ΔABC, the corresponding sides of the two triangles are proportional. Therefore, BC will not be equal to AC in general. This option is incorrect.

b. BC = XY

This option assumes that BC is equal to XY. Since point X is between points A and B, and point Y is between points A and C, BC does not directly correspond to XY. This option is also incorrect.

c. BC equals XY times AX over AB

This option uses the concept of similarity to find the length of BC. We can write the proportion between corresponding sides as:

BC/XY = AB/AX

To solve for BC, we multiply both sides of the equation by XY:

BC = (AB/AX) * XY

This expression tells us that BC is equal to XY multiplied by the ratio of AB to AX. This option is correct.

d. BC equals XY times AB over AX

This option incorrectly switches the positions of AB and AX in the ratio. Therefore, it is incorrect.

To summarize, the correct expression to determine the length of segment BC is option c: BC = XY * (AB / AX).

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
